Muscle loss in dogs can sneak up quietly—and by the time it’s obvious, your pup may already be struggling. Whether your dog is aging, recovering from injury, or simply less active lately, it’s important to recognize the early signs of muscle atrophy and take action. Here are 5 subtle signs your dog might be losing muscle:

1. A Dip in Energy or Stamina

If your dog tires more quickly on walks or hesitates to play like they used to, it could be more than just aging. Muscle loss often reduces endurance.

2. Noticeable Weight Loss—But the Belly Looks the Same

Losing muscle can make dogs appear thinner in the hindquarters or shoulders, even if their body weight stays stable.

3. Trouble with Stairs or Jumping

Difficulty climbing stairs, getting on the couch, or hopping into the car could point to weakening muscles—especially in the back legs.

4. Slower Recovery After Exercise

If your dog is sore or stiff longer than usual after activity, it may be a sign their muscles are not recovering as efficiently as they once did.

5. Uneven Gait or Favoring One Side

Muscle imbalance or atrophy on one side can cause limping, stiffness, or a strange walking pattern.
